Revisiting my new system one month later
My old system: '95 vintage Goodman Janitrol heat pump installed by home builder.
My new system: 15/16 SEER Maytag heat pump with VS AH and two stage compressor.
Energy usage, old system:
January: 3032 KWH, average temp 60
February: 3014 KWH, average temp 59
Energy usage, new system, first 30 days:
Feb 12-March 13: 2128 KWH
I don't have the average temp data for this period, but it will be on my electric bill when it arrives in a few days. We've had some pretty cold days in the last month.
So far, I am VERY happy. I am anxious to see how the system performs when it is time to switch to cooling.
Again, I want to thank everyone on this forum. Info that I picked up here helped me to decide on which system and contractor to use.
Your cooling costs should be much less than heating since bitter cold winter temps require back-up electric heat from the strips.

Best to you.
